Solve the all parts of given problem:

Problem: A student decides to move a box of books into her dormitory room by pulling on a rope attached to the box. She pulls with a force of 160 N at an angle of 32^o above the horizontal. The box has a mass of 25.2 kg, and the coefficient of friction between box and floor is 0.275. The acceleration of gravity is 9.8 m/s².

Part A: Find the acceleration of the box.

Answer in units of m/s²

Part B: The student now starts moving the box up a 10.8 m incline, keeping her 160 N forces directed at 32o above the line of the incline. If the coefficient of friction is unchanged, what is the new acceleration of the box?

Answer in units of m/s²
